“My reaction is this,” Limbaugh said on his national broadcast Tuesday.

“If Hillary has brain damage, what difference does it make now? What possible difference does it make now? How it happened or even if she has brain damage.”

Limbaugh’s quip echoed remarks by Mrs. Clinton when President Obama’s former secretary of state was grilled about the fatal onslaught at the U.S. mission in Benghazi, Libya, on Sept. 11, 2012.

During her testimony in January 2013, Clinton said, “With all due respect, the fact is we had four dead Americans. Was it because of a protest or was it because of guys out for a walk one night who decided that they’d they go kill some Americans? What difference at this point does it make?”

Noting reports Mrs. Clinton had suffered a blood clot after a fall in December 2012, the New York Post reported Rove said, “Thirty days in the hospital? And when she reappears, she’s wearing glasses that are only for people who have traumatic brain injury? We need to know what’s up with that.”

Rove is now distancing himself from the remark, telling the Washington Post on Tuesday, “Of course she doesn’t have brain damage.”

But Rove told the Washington Post it’s apparent Clinton suffered “a serious health episode,” adding if she jumps in the 2016 presidential race, “she is going to have to be forthcoming” on details of where, how and when it happened.

“She didn’t feign illness,” Rove said of Clinton’s failure to appear at an early round of congressional hearings on Benghazi, an absence referred to by some as “Benghazi flu.”

A representative for the former first lady was quoted as saying, “Please assure Dr. Rove she’s 100 percent.”

Limbaugh noted, “The left is fit to be tied over what Rove said about Mrs. Clinton.”

The broadcaster suggested, “If you’re gonna start going down this road with Mrs. Clinton, you gotta go back a lot farther than December of 2012. I mean, you remember how Hillary couldn’t remember where she put the Rose Law Firm billing records. She couldn’t remember how she got a hold of those 900 FBI files that she and Bill had somewhere.”

Sound off on suggestion that Hillary Clinton has brain damage

It's mean-spirited and typical of Republicans to lie

The GOP must really be scared of her to raise such a claim

It's a foul canard put out there for political purposes

Hillary Clinton is a great public servant and I believe her and her staffers who say she’s operating at '100%'

I don't like Hillary Clinton, but brain damage is a tragedy and nothing to joke about

As the presumptive Dem presidential nominee, she has an absolute obligation to come clean on this

She should publicly release the medical records surrounding her recent cranial 'blood clot'

Hillary has always had something seriously wrong with her brain, so I'm not sure, at this point, what difference it makes

She has a history of not remembering key facts about the Rose Law Firm, so her brain was already damaged

She's a liberal, so her brain is naturally warped

I think it's quite possible that her brain did sustain a serious injury when she fell in 2012

Oy! That's all we need. She's already the closest thing we have to a genuine sociopath in today's U.S. politics
